ATTENTION: Allow only qualified personnel to perform the following tasks. Observe and follow the safety instructions in this document and all other related documentation. Introduction Intended Use Applicators of the series SB60-BoD may be used only to apply PUR and other hot melt adhesives commonly used in the book binding industry to glue the spines of books. Any other use is considered to be unintended. Nordson will not be liable for personal injury and/or property damage resulting from unintended use. Intended use includes the observance of Nordson safety instructions. Nordson recommends obtaining detailed information on the materials to be used. Unintended Use - Examples - The applicator may not be used under the following conditions: In defective condition When changes or modifications have been made by the customer In a potentially explosive atmosphere When unsuitable material is used When the values stated under Technical Data are not complied with. The applicator may not be used to process the following materials: Explosive and flammable materials Erosive and corrosive materials Food products.
2 Applicator Residual Risks In the design of the unit, every measure was taken to protect personnel from potential danger. However, some residual risks cannot be avoided. Personnel should be aware of the following: Risk of burns on the hot applicator: from hot material and when making adjustments Material fumes can be hazardous. Avoid inhalation. Note on Manual Definition of Terms Applicator The term application head is also used in Nordson literature. Melter General term for tank melters and bulk melters. Control Module The term module is also used in Nordson literature.
Applicator 3 Applicator Components 1 2 8 3 4 7 6 5 6 Fig. 1 1 Handwheel Application width 2 Power cable (heater) 3 Air connection Solenoid valve 4 Solenoid valve 5 Control module 6 Guide plate 7 Hose connection 8 Screw plug
4 Applicator Function A melter pumps the material through a heated hose and into the applicator. The material is applied to the spine from underneath as soon as the Control module (1 ) is triggered (opened). The application width can be set continuously up to 60 mm. CAUTION: Do not set the application width to be greater than 60 mm. Otherwise the lateral guide plates can be damaged. 2 1 5 4 3 Fig. 2 1 Control module 2 Guide plates 3 Application slot 4 Hose connection Material inlet 5 Handwheel Application width Side Gluing 3 mm If the guide plates (2, Fig. 2) have a groove (Side gluing slot), material is also applied laterally. NOTE: Refer to the separate Parts List, Service Kits for the different guide plate models. CAUTION: When mounting the guide plates, apply high temperature grease to the surface between the guide plate and the body. Refer to page 28, Processing Materials! Groove (1 mm x 3 mm) for side gluing
Applicator 5 Volume Control The motion of two restricting pistons reduces the volume in the distribution channel when the application width is decreased; it increases to the same degree in a compensating chamber. By equalizing the volume, no material escapes and no air is sucked in when the application width is modified. So material is applied precisely beginning with the first book. Heating Electrical heater cartridges are used to heat the unit. The temperature is continuously measured by temperature sensors and is regulated by electronic temperature controllers. The temperature controllers are usually not part of the applicator. They are located in the melter electrical cabinet. Overtemperature Shutdown by Thermostat A thermostat in the body switches off the heater at approx 230 C or 180 C, depending on the model.

6 Applicator Installation ATTENTION: Allow only qualified personnel to perform the following tasks. Observe and follow the safety instructions in this document and all other related documentation. Unpacking Unpack carefully. Then check for damage caused during transport. Reuse packaging materials or dispose of properly according to local regulations. Transport The applicator is a high precision, valuable part. Handle very carefully! Protect the nozzle from damage. Storage Do not store outside! Protect from humidity and dust. Protect the nozzle from damage. Installing When installing the applicator, the following points should be observed in order to avoid unnecessary effort later. Protect from humidity, vibrations, dust and drafts Ensure access to parts relevant for maintenance and operation When installing the unit, ensure that cables, air hoses and heated material hoses can not be bent, pinched, torn off or otherwise damaged. Exhausting Material Vapors Ensure that material vapors do not exceed the prescribed limits. Exhaust material fumes when necessary. Provide sufficient ventilation of the location where the unit is installed.
Applicator 7 Attaching to Parent Machine Screw the applicator onto the separate bracket (provided by the customer) in the parent machine. Observe when Attaching The application slot must be at a right angle to the direction of movement of the book spine. The inside edge of the rear book clamp must be aligned to the immobile guide plate of the applicator. Adjusting Parallelism and Application Thickness NOTE: A sensor gauge for adjusting the application thickness is contained in the Ship with kit. To achieve even application, adjust the applicator such that the application slot is parallel to the book spine. Adjust parallelism and the desired application thickness on the customer's bracket. NOTE: The application thickness on a book spine can be measured with the included measuring magnifier.
8 Applicator Electrical Connection ATTENTION: Observe voltage values found on the ID plate of the applicator and solenoid valves. ATTENTION: Risk of electrical shock. Failure to observe may result in personal injury, death, or equipment damage. Laying Cable ATTENTION: Ensure that cables do not touch rotating and/or hot components. Do not pinch cables and check regularly for damage. Replace damaged cables immediately! Heater 1. Connect the plug (1) to the melter electrical cabinet or to an external electrical cabinet. 2. Use safety clips - when available - to secure the plug connection. 1 Fig. 4 Solenoid Valve Connect the solenoid valve to a pattern controller. NOTE: Connecting lines can be part of a special cable harness.
Applicator 9 Pneumatic Connection Connect the applicator only to pressure-controlled and conditioned compressed air. Connecting Control Air 1. Connect the control module to the customer's air conditioning unit. 2. Set air pressure to 6 bar / 0.6 MPa / 87 psi. Connecting Heated Hose Using Second Open-end Wrench Use a second open-end wrench when connecting and disconnecting the heated hose. This prevents the hose connection on the unit from turning. If cold material can be found in the hose connection, these components (1, 2) must be heated until the material softens (approx. 70 C /58 F, depending on the material). CAUTION: Nordson melters are subjected to extensive testing prior to shipment. There may be some of the test material left in the hose connection. Fig. 5 Connecting 1 2 3 ATTENTION: Hot! Risk of burns. Wear heat-protective gloves. 1. First connect the hose (3) electrically. 2. Heat applicator and hose until the material softens. 3. Screw on heated hose. Fig. 6
10 Applicator Connecting Heated Hose (contd.) Disconnecting ATTENTION: System and material pressurized. Relieve system pressure before disconnecting heated hoses. Failure to observe can result in serious burns. ATTENTION: Hot! Risk of burns. Wear goggles and heat-protective gloves. Relieving Material Pressure 1. Set the motor speed of the unit feeding the material to 0 min 1 (rpm); switch off motor(s). 2. Place a suitable container under the nozzle of the applicator to collect the adhesive. 3. Activate the solenoid valve electrically or manually (arrow). Do not use sharp objects! Repeat this procedure until no more material flows out. 4. Properly dispose of material according to local regulations. Fig. 7
Applicator 11 Motorizing Application Width Adjustment Observe the following when mounting a motor drive for adjusting the application width: CAUTION: Risk of injury from moving parts! Protect from direct contact. Comply with these values: Minimum torque [Nm] required Recommended maximum spindle speed * [min -1 ] 2 318 NOTE: * Higher speeds increase wear to seals and bearing surfaces.

12 Applicator Operation ATTENTION: Allow only qualified personnel to perform the following tasks. Observe and follow the safety instructions in this document and all other related documentation. Important When Using Polyurethane Application Materials (PUR) Triggering Solenoid Valve Setting Temperature Maximum Operating Temperature It is imperative that the following guidelines are complied with when processing polyurethane application materials (PUR): Wear respiratory protection when the maximum permissible concentration of hazardous substances is exceeded. Before prolonged standstill of the application system, purge with a suitable cleaning agent. Use only a cleaning agent recommended by the material manufacturer. Close open material connections airtight. When the system is to cease operation for only a short time, it suffices to coat the application slot generously with grease. CAUTION: Use only special high temperature grease. Refer to page 28, Processing Materials! Any other grease may cause the PUR material to cross link. CAUTION: Trigger the solenoid valve only when the applicator is heated to operating temperature! If the material is too cold, control module seals may be damaged. The procedure for setting the temperatures is described in the temperature controller manual. The temperature controller is not part of the applicator. They can be located e.g. in the electrical cabinet of the melter or in a separate electrical cabinet. 180 C / 356 F NOTE: The temperature setting is determined by the processing temperature prescribed by the material supplier. The maximum operating temperature for the product described here and the heated system components may not be exceeded. Nordson will grant no warranty and assume no liability for damage resulting from incorrect temperature settings.
Applicator 13 Material Application Factors that have a significant influence on application quality: Viscosity of the material (The heat effect and the duration thereof influence the viscosity) Material pressure (application pressure). It has to be determined by trial and error and then set depending on the desired application thickness, the application width, the machine speed and the adhesive viscosity. Medium application widths have proven to require a lower material pressure than small or large application widths Book spine condition. Setting Application Width CAUTION: Do not set the application width until the applicator is heated to operating temperature. CAUTION: Do not set the application width to be greater than 60 mm. Otherwise the lateral guide plates can be damaged. + 1. Set the application width to the width of the book spine + 0.3 mm: 2. Re adjust application width during operation if required. - Fig. 9
14 Applicator Daily Shutdown To prevent the PUR material to be processed from hardening, open surfaces must be coated with grease. CAUTION: Use only special high temperature grease.
